Frequently Asked Questions

Below are some of our most asked questions. Get in touch if you have more questions.

Is there any sample JSON (or XML) data that shows the response from your API?

Although most requests made to our application request a JSON response, we also have the ability to return XML from our JSON API. This option is available on all subscription plans.

Its super easy to change the output of the response when calling our exchange rate XML API. All that's needed is adding or modifying the output parameter in the URL and as long as you apply a correct value and a valid API key, you will get the response your looking for.

An example request to our rates API would look like this:

https://currencyapi.net/api/v2/rates?key=YOUR_API_KEY&output=XML

This will return reliable currency exchange rate data from our exchange rate XML API. Developers will then be able to parse this XML response and convert it into something your application can read.

Is there example code available?

Getting started with our currency exchange rate API can be done in seconds. We supply example exchange rate code so developers can get reliable currency data straight away.

So which languages do you supply example code? Python, NodeJs, GoLang / Go, PHP, cUrl, Ruby, Java, jQuery and Javascript.

To see how this works, head over to our documentation page and using the tabs, select which language you want to see the example exchange rate code. Within minutes, you will have access to real time, accurate and reliable exchange rate data. Because our application is a JSON API by default, it doesn't matter which programming language or framework your application uses, your application will be able to work with the response easily.

We also supply example code when using our premade packages in both PHP and NodeJs. Using composer or NPM you get access to our premade methods making it even easier to interact with our API.

Is the exchange rate data live?
